Must-Knows About DevOps, Cisco Open NX-OS and Ansible

You may wonder what the terms “DevOps, Cisco Open NX-OS and Ansible” have to do with each other. If you plan to visit AnsibleFest 2015 in San Francisco, stop by the Cisco table to learn more.


The DevOps approach has been embraced and pioneered by Web 2.0 customers for some time, and now we’re seeing the trickle of that coming to an Enterprise customer near you. The simple reason is the ability to bring operations and development closer together, enabling faster deployments of applications without breaking the infrastructure. Cisco colleague Luca Relandini expands on DevOps here.

The Cisco Open NX-OS is designed to support the DevOps approach. Shane Corban shares Six Key Points What OPEN means for NX-OS. The concept behind Open NX-OS is to enable operators to make changes in a more programmatic way that drives automation and efficiency in the infrastructure without compromise on security. Visit the developer community to learn and find more scripts using the capabilities of Open NX-OS.

OpenNXOS Nov2015

As part of the NX-OS openness, agentless tools like Ansible leverage NX-API to gather real-time state data and to make configuration changes on Cisco Nexus switches. To stay up to date on Ansible solutions, visit the Cisco marketplace.

In this Oct 9th SDxCentral DemoFriday webinar, we showed how Day 0, 1, 2 operations can be accelerated with Ansible. And to stay up to date on the latest Cisco NX-OS Ansible Module Docs, visit the GitHub repository.

Server Load balancing with NAT, using Nexus switches: ITD

Server load balancer (SLB) has become very common in network deployments, as the data & video traffic are expanding at rapid rate. There are various modes of SLB deployments today. Application load balancing with network address translation (NAT) has become a necessity for various benefits.

Cisco Intelligent Traffic Director (ITD) is a hardware based multi-terabit layer 4 load-balancing and traffic steering solution on the Nexus 5k/6k/7k/9k series of switches.

With our latest NX-OS Software 7.2(1)D1(1) (also known as Gibraltar MR), ITD supports SLB NAT on Nexus 7k series of switches.

In SLB-NAT deployment, client can send traffic to a virtual IP address, and need not know about the IP of the underlying servers. NAT provides additional security in hiding the real server IP from the outside world. In the case of Virtualized server environments, this NAT capability provides increased flexibility in moving the real servers across the different server pools with out being noticed by the their clients. With respect health monitoring and traffic reassignment, SLB NAT helps applications to work seamlessly without client being aware of any IP change.

ITD won the Best of Interop 2015 in Data Center Category.


ITD provides :

  1. Zero latency load-balancing.
  2. CAPEX savings : No service module or external L3/L4 load-balancer needed. Every Nexus port can be used as load-balancer.
  3. IP-stickiness
  4. Resilient (like resilient ECMP), Consistent hash
  5. Bi-directional flow-coherency. Traffic from A–>B and B–>A goes to same node.
  6. Monitoring the health of servers/appliances.
  7. Handles unlimited number of flows.

Halloween can be scary. Automating your network doesn’t need to be.

Some random, yet strangely connected, thoughts the night before Halloween…

  1. Zombies can be scary:


  1. Death Metal* can be scary:

Click here to listen.

  1. Learning new skills and using new tools to automate your network can appear to be scary if you don’t have a coding background. But that doesn’t need to be the case…

In a previous blog post, I discussed Cisco’s SDN Strategy for the Data Center. I mentioned that it is built on 3 key pillars: Application Centric Infrastructure, Programmable Fabric, and Programmable Network. Regarding the 3rd pillar, I wrote that network programmability has largely been the domain of big Web SP’s, and/or those whose propellers seen to spin faster than others. However, the reality is that tools are available that are useful for networks of pretty much any size, and the tools are within reach of pretty much everybody.

Rather than rattle off a list cool features that are part of Programmable Network (some of which are summarized here), I thought it more useful to consider common things network people actually do on a daily basis, then show how we can apply programmability tools to do those things with, for lack of a better phrase, “the 3 S’s”:

  • Speed – enabling you to do things much faster;
  • Scale – enabling you to do things to a much larger group of devices; and
  • Stability – enabling you to make far fewer errors (thereby also increasing Security…oops, now that’s 4 S’s…)

In upcoming posts, we will consider use cases such as switch provisioning. For example, you need to put a bunch of VLANs on a bunch of switches. Unless you have a battalion of minions to carry out your wishes, this can be a tedious, time consuming task. There is a better way, and we’ll show you how.

What’s that? You say you’re a network geek, but you moonlight as a server admin? You’ve been using Linux tools to monitor and troubleshoot servers and want to use the same tools for the network? Okay, we can cover that too because tools like ifconfig and tcpdump are all part of the party.

If you can’t wait for the future posts and/or you want to dive deep, this recorded webinar should tide you over.

Anyhow, I need to go carve a pumpkin now…Happy Halloween!

*For music aficionados…Yeah, I know – the link was Heavy Metal not Death Metal, but I used one of my own songs…and this is about as close to Death Metal as I get. That whole guttural screaming thing never worked for me…
